Can you really learn to bowl a Dusra by seeing a delivery?? then you could learn a reverse, Yorker everything by watching the footage.... Man, you need to know the physio dynamics of bowling a delivery... Well some people might just be able to learn certain things using their natural abilities. But for any established bowler to tweak his physio dynamics in an uncontrolled environment, might ruin his current abilities... So you don't try to learn a new thing as a pro, in an uncontrolled environment. That's why people employ professional coaches.

A non swimmer can't learn swimming just by watching an Olympic swimmer. He needs assistance of some sort, before he starts even self learning... Every skill is like that. You don't learn skills by watching... By doing .. And for professionals.. You must control the environment of learning.... Otherwise that can be damaging or counter productive.

...can't say it better. But you also need to work very hard and practise a lot from your early days. The value of expertise is something we spend a lot of time thinking about and if you’ve read the Malcolm Gladwell book Outliers, you’re familiar with the idea that it takes thousands of hours to perfect a skill. Having years (and thousands of hours) of dedicated focus and practice within a specific field is obviously highly valuable and allows a person to have a unique, proprietary perspective on that area.
